Engineers thumb. Switch wiring?

[adam193]

Making an engineers thumb on vero.

There are two wires for the switch. My switch has three posts. Which do I solder to?

Thanks. Ad

A link to your vero build would be nice.

Just wire One on the outside and the middle one.

[adam193]

Assuming either outside is 1 and the middle is 2,  right?
